Established executives are often resistant to strategic reorientations (Miller, 1991; Wiersema & Bantel, 1992). Drawing on the upper echelons perspective, latest research unveils the important role of CEO turnover in enhancing firms’ entrepreneurial orientation (EO) (Li et al., 2008; Grühn et al., 2016). However, research on entrepreneurship lacks an understanding of the impact of collective top management team (TMT) turnover on EO. Consequently, this study aims at answering a critical question for advancing EO and TMT research: What is the association between collective TMT turnover and changes in EO?
